5. Steve Mazzagatti: Yves Edwards vs. Josh Thomson at UFC 49

This list simply could not claim legitimacy without an entry for Steve Mazzagatti.

There are many bad calls to choose from when it comes to Dana White's favourite referee, but his criminally late stoppage of the bout between Yves Edwards and Josh Thomson is amongst his most blatant transgressions.

You may recognise the end of this fight from the UFC’s famous Baba O’Riley highlight package at the start of each event.

Edwards secured standing back control and, rather than attempt a throw, leapt into the air and delivered a head kick that knocked Thomson silly.

Mazzagatti remained unconvinced of what appeared obvious to the rest of us. To be fair, he simply wanted to make sure that Thomson was dead, and so allowed Edwards to deliver a succession of piston-like left hands to the defenceless AKA veteran.

It was a truly horrific image, but one that is not entirely unexpected when you hear Steve Mazzagatti’s name announced at the start of a fight.

4. Josh Rosenthal: Chris Weidman vs. Mark Munoz at UFC on Fuel TV 4

Unfortunately, this particular call tarnished an evening that would have been memorable for all the right reasons, with Chris Weidman announcing himself as a potent force in the middleweight division.

It all started with a beautifully timed elbow that sent Munoz crashing to the mat, clearly in no condition to continue. However, we could have forgiven Rosenthal for allowing Mark Munoz a few extra seconds to recover.

The problem is that Josh didn’t feel that a few seconds was enough time for him to assess Munoz’s condition. Either that or he has unshakable faith in the former national champion wrestler’s ability to battle back from adversity.

Indeed, had Munoz somehow survived the Weidman onslaught that followed the elbow, he would have demonstrated the kind of bouncebackability—yes, it’s a word—not seen since Lazarus.

Weidman continued to hammer Munoz as he lay prone on the mat, until finally Rosenthal stepped in with all the urgency of a sedated tortoise.
